Andrew Purtell commented on HBASE-13124:
----------------------------------------
Agree with Nick. Hypothetically, if we had a more generally useful HTable
wrapper that measured invocations and hooked this up to metrics, then the PE
option for measuring per op latency would be trivial to implement.

> Project: HBase
> Issue Type: Improvement
> Components: Performance, test
> Affects Versions: 0.98.6
> Reporter: Hari Krishna Dara
> Attachments: HBASE-13124-1.patch

>
> Currently, the only option in {{PerformanceEvaluation}} is to print latency
> percentile summary at the end, and it is also not suitable if we are testing
> for a long duration (as all the timings are collected in memory). There
> should be an option to dump the latencies with a timestamp as CSV to a file
> so that this allows a detailed analysis on the generated data, such as:
> - Percentile calculation at the desired precision on the latencies
> - Latencies over time
> - Histograms
